Def sounds like a bubble to me. In my own bubble, ChatGTP is so well known over the others that people will often slip and refer to other AI services collectively as ChatGTP.
e.g. "I put it in chatgtp and..." when they actual asked Gemini.

Still everyone knows what I'm talking about.
The people in real life who say ChatGBT or similar are either so out of the loop the technology doesn't even matter to them, or simply are just stupid.
There is no way a person who can't get "GPT" right is even worth listening to.
